TRA1309CP - Functional Speaker Driver

Datasheet Summary

Description

TRA1309CP is a speaker amplifier that can accept PWM signal and doesn’t need any external device for these input signals.

PWM input supports mainly for TRITAN’s PWM output.

The TRA1309CP contains advanced de-pop circuitry which eliminates pops during chip enable and disable.

Functional Speaker Driver TRA1309CP 1. General Descriptions TRA1309CP is a speaker amplifier that can accept PWM signal and doesn’t need any external device for these input signals. PWM input supports mainly for TRITAN’s PWM output. The TRA1309CP contains advanced de-pop circuitry which eliminates pops during chip enable and disable. The gain is adjusted by connecting an external resistor between RGAIN and SPKN. Internal sound processing is added for better sound quality. 2. Features z Accept PWM and doesn’t need any external devices for these input signals. z Mute function z Wide operation voltage : 2.4V~5.5V z sound processing for better sound quality z Auto power ON/OFF z Low standby current : 2u A, typical. z High output power Pout = 0.8W (VDD=5.5V, THD=1%) 3.
